New England groundfish sectors, a kind of a catch share management system, are entering their third week of operation. It’s far too early to pass judgment, but here’s what we’re watching for: 1) The ability of individual fishermen to maximize their profits and minimize their costs, and 2) The total 2010 harvest of groundfish compared to annual catch limits (ACLs). An article from SeafoodNews.com that we cited last week discussed these two measures, but was criticized for comparing the first week of landings versus last year’s harvest. However, since fishermen fishing under sectors no longer have any time constraints to their harvests, weekly landings are not a meaningful measure of success or failure.
